过硫酸钠用途主要有哪些

来源:http://www.jnjhhg.cn/ 日期:2022-08-03 发布人: 浏览次数:0
过硫酸钠外观为白色结晶性粉末状,易溶于水,在潮湿和高温能使分解加速;能被乙醇和银离子分解,在20℃时水中溶解度为549g/L;过硫酸钠也易潮解,在湿空气中和高温都能加速过硫酸钠分解,放出氧而变为焦硫酸钠。
The appearance of sodium persulfate is white crystalline powder, which is easily soluble in water and can accelerate decomposition in humidity and high temperature; It can be decomposed by ethanol and silver ions, and the solubility in water is 549g/l at 20 ℃; Sodium persulfate is also prone to deliquescence. In wet air and high temperature, it can accelerate the decomposition of sodium persulfate, release oxygen and become sodium pyrosulfate.
过硫酸钠用途主要有哪些
What are the main uses of sodium persulfate
过硫酸钠溶液呈酸性反应,能被醇和银离子分解,还能与可燃物或易氧化物发生燃烧,并能助燃、助长火势,剧烈时甚发生爆炸。存放时会慢慢分解,过硫酸钠溶液在室温下已有明显分解,具有强氧化性。
Sodium persulfate solution has an acidic reaction, can be decomposed by alcohol and silver ions, can also burn with combustibles or easy oxides, and can support combustion, contribute to fire, and even explode when it is violent. It will decompose slowly during storage. Sodium persulfate solution has been significantly decomposed at room temperature and has strong oxidation.
那么,过硫酸钠用途都有哪些呢?
So, what are the uses of sodium persulfate?
过硫酸钠用途主要用作漂白剂、氧化剂、乳液聚合促进剂。还可用于照相业的废液处理,用作印刷电路板表面金属的软蚀剂及纺织用脱浆剂、硫化染料发色剂等。用作油井压裂液的破胶剂、电池去极化剂及有机高分子乳化聚合引发剂。照相工业用于胶片显影、定影剂;还可用作废液处理剂、金属表面处理剂、印刷电路版的蚀刻剂等。
Sodium persulfate is mainly used as bleaching agent, oxidant and lotion polymerization promoter. It can also be used for the treatment of waste liquid in the photographic industry, as a soft etchant of metal on the surface of printed circuit boards, as a desizing agent for textiles, a sulfur dye chromogenic agent, etc. It is used as gel breaker of oil well fracturing fluid, battery depolarizer and initiator of organic polymer emulsion polymerization. In the photographic industry, it is used as film developer and fixer; It can also be used as waste liquid treatment agent, metal surface treatment agent, etching agent of printed circuit board, etc.
如存储不当,会导致过硫酸钠用途大大降低,所以过硫酸钠应储存于阴凉、干燥、通风良好的库房。远离火种、热源。库房温度不超过30℃,相对湿度不超过80%。使用完后包装要密封,要与还原剂、活性金属粉末、碱类、醇类等分开存放,切忌混储。
Improper storage will greatly reduce the use of sodium persulfate, so sodium persulfate should be stored in a cool, dry and well ventilated warehouse. Keep away from kindling and heat sources. The temperature in the warehouse shall not exceed 30 ℃, and the relative humidity shall not exceed 80%. After use, the package should be sealed and stored separately from reductants, active metal powders, alkalis, alcohols, etc. do not mix them.
